结论：使用硅胶管和麦克风可以在尸体中进行围手术期噪音记录，并且在体内应用应该是安全的。我们的初步数据表明，内耳手术期间的噪音水平达到可导致噪音性听力损失的水平。我们的方法很容易执行，并使未来的简单和安全的噪音记录，我们建议未来的应用在体内扩大知识的围手术期噪音水平。目的：旨在评价中耳手术期间连接至麦克风探头的硅胶管在噪声记录中的安全性和实用性，并获得关于钻相关噪声水平的初步结果。研究方法：通过连接到麦克风的硅胶管和Matlab（R）计算机程序，在乳突切除术期间和在尸体模型中的耳蜗造口术期间的圆窗处获得围手术期噪声记录。结果如下：我们的方法能够记录靠近钻头的辐射噪声水平，在皮质骨钻孔期间范围为84至125 dB SPL，在乳突腔钻孔期间范围为85至117 dB。在耳蜗造口噪声水平范围从114至128分贝SPL时，录音接近圆窗。由于麦克风过载超过80 Pa，最大噪声水平被低估。
Conclusion: The use of a silicone tube and a microphone enables peroperative noise recordings in cadavers and should be safe to apply in vivo. Our preliminary data indicate that noise levels during inner ear surgery reach levels that can cause noise-induced hearing loss. Our method is easily performed and enables future uncomplicated and safe noise recordings and we suggest future application in vivo to expand knowledge regarding peroperative noise levels. Objectives: To evaluate the safety and utility of a silicone tube connected to a microphone probe in noise recordings during middle ear surgery and to achieve preliminary results regarding drill-related noise levels. Methods: Peroperative noise recordings were obtained during mastoidectomy and at the round window during cochleostomy in a cadaver model by means of a silicone tube connected to a microphone and a Matlab (R) computer program. Results: Our method enabled recordings of radiated noise levels close to the drill ranging from 84 to 125 dB SPL during drilling in cortical bone and from 85 to 117 dB during drilling in the mastoid cavity. During cochleostomy noise levels ranged from 114 to 128 dB SPL when recordings were made close to the round window. Maximal noise levels were underestimated due to microphone overload above 80 Pa.
